Investigation TTRPGs need to keep clues, interpretation, danger, and momentum in balance. Start with Call of Cthulhu, Delta Green, Kult: Divinity Lost, and Monster of the Week as comparison points, then move down the list based on the kind of mechanical focus your group actually wants.
When comparing investigation games, look at clue guarantees, information flow, whether failure blocks progress, how mysteries escalate, and whether the game favors deduction, procedures, or character drama. Those details matter more than the tag itself, because two games can share a category while asking completely different things from the GM and players.
Use the top picks as anchors rather than treating the page like a simple popularity ranking. The goal is to answer the practical table question: which game will produce the kind of first session, campaign rhythm, and player buy-in your group is likely to enjoy?
Avoid games where a missed roll can stop the case cold unless the GM has strong fallback tools.
Quick starting points if you want the clearest expressions of what Investigation games do well.
Start with Call of Cthulhu when you want a investigation option that makes the category visible in play, not just in premise.

Choose by the job at the table. For investigation TTRPGs, compare clue guarantees, information flow, whether failure blocks progress, how mysteries escalate, and whether the game favors deduction, procedures, or character drama. If that sounds too abstract, ask what the game makes players decide in the first hour.
Use the top picks as contrasts. Call of Cthulhu and Delta Green are useful side-by-side because they show different ways this category can work. Kult: Divinity Lost adds another angle, while Monster of the Week helps test whether your table wants a different commitment level.
Match scope before rules. Some investigation games are best as one-shots, some need a short arc, and some only reveal their strengths through campaign play. Decide that scope first, then choose the rules weight your group will actually tolerate.
Investigation is central to Monster of the Week because the hunters need answers before the final fight works. The game rewards asking sharp questions, following leads, and turning partial information into risky plans.
Kult: Divinity Lost fits investigation when disappearances, cults, occult traces, and compromised witnesses are the route into the game's deeper cosmology, even though it is less procedural than Delta Green or Call of Cthulhu.
Bluebeard's Bride fits Investigation because sessions revolve around opening rooms, examining objects, questioning servants, and assembling what happened to the earlier brides before the final choice.
